ERROR: opening '/.../rra/pix515_traffic_in_8.

I am new to this, so be gentle :-]

I wasn't getting any graphs, so I turned on Graph debugging. It was unable to write to a log file, so I fixed the permissions. Now it says

ERROR: opening '/var/www/html/cacti/rra/pix515_traffic_in_8.rrd': No such file or directory

I waited for a while for cron to run. I even (in webmin) manually ran the cron job. Somebody mentioned something about a config file change to point to the RRD tool location. Is this my next step? Where do I edit it if so? If not, what do you recommend?

OK, i found the path to RRDtool in Cacti Settings --> Path. The path is good. Any suggestions?

I ran php.cmd and got this:

There are no items in your poller cache. Make sure you have at least one data source created. If you do, go to 'Utilities', and select 'Clear Poller Cache'.
time: 0

I see that my snmp cache is empty.

Does this necessarily mean that I am not polling or could I have something pointing in the wrong direction? If so, what can I do to debug polling? I have a data source configured already and I can manually run the cron job.

I verified that I can snmpget from this target using command line with the same community string:

# snmpget -v 1 10.3.17.254 -c test ifDescr.2
IF-MIB::ifDescr.2 = STRING: PIX Firewall 'inside' interface

What I am after is interface throughput which I don't know the syntax for but I think it should work anyway, right?

OK, I found out where to debug the data source (data source --> debug on).

It shows that polling is working, so I think I am down to "Why isn't that info making it into my polling cache?" Does that sound right? Any suggestions?

Here is my cron log stuff:

Looks like it's working, eh?

My paths to snmp utilites are correct:

snmpget: /usr/local/bin/snmpget
snmpwalk: /usr/local/bin/snmpwalk
